21、ting a.c. machines FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning sta
22、ndardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their prepara
23、tion is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely wit
24、h the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subj
25、ects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical
26、 content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent p
27、ossible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any eq
28、uipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and
29、 IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) At
30、tention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights.
31、 IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60034-15 has been prepared by IEC technical committee 2: Rotating machinery. This third edition cancels and replaces the second edition published in 1995 and constitutes a technical revision.
32、 The principal technical changes are as follows. Change of title to clarify that it is form-wound coils that are being tested rather than machines. Removal of the limitation on voltage in the Scope. Additional definitions for consistency with IEC 60060-1. Reduction in tolerances for the risetime of
33、the steep-fronted impulse voltage. Guidance on test levels for coils to be used in converter driven machines. Guidance on voltage levels for routine tests. Additional figures to show testing details and oscillograms of normal and faulty coils. BS EN 60034-15:2009 4 60034-15 IEC:2009 The text of this
34、 standard is based on the following documents: FDIS Report on voting 2/1534/FDIS 2/1547/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives,
35、 Part 2. NOTE A table of cross-references of all IEC TC 2 publications can be found on the IEC TC 2 dashboard on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the maintenance result date indicated on the IEC web site under “http:/webstor
36、e.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. BS EN 60034-15:200960034-15 IEC:2009 5 INTRODUCTION IEC 60071-1 specifies general requirements for the phase to earth insulation of equi
37、pment in three phase a.c. systems and states that each apparatus committee is responsible for specifying the insulation levels and test procedures for its equipment, taking into consideration the recommendations of IEC 60071-1. The object of IEC 60034-15 is to specify requirements for rotating elect
38、rical machines. Experience has shown that the values given in this standard meet the insulation requirements for the essential stresses in service. An explanation of the principles adopted in preparing these requirements is given in Annex A. This standard is not intended for soft-start machines. BS

It specifies the test procedures and voltag
40、es to be applied to the main and interturn insulation of sample coils. 2 Terms and definitions For the purposes of this document the following terms and definitions apply. 2.1 sample test test carried out on coils in new condition which adequately represent the configuration of the finished item to
41、be used in the machine for the purpose of evaluating the manufacturing procedures and processes incorporated in the insulation system 2.2 routine test test carried out on all coils of the machine 2.3 form-wound stator coil coil which is preformed to shape, insulated and substantially completed befor
42、e insertion into the stator 2.4 front time T1time for the impulse voltage to rise from 0 % to 100 % of the peak value and defined as 1,67 times the interval between the instants when the impulse is 30 % and 90 % of the peak value 2.5 time-to-half value T2 interval between the origin and the instant
43、when the voltage has decreased to half the peak value 3 Impulse voltage withstand levels Impulse voltage withstand levels for specific rated voltages shall be calculated in accordance with the formula given in Note 2 of Table 1. Table 1 gives the impulse voltage withstand levels for some common rate
44、d voltages rounded to the nearest whole number. The test levels for converter-fed machines depend upon how the rated voltage has been assigned by the manufacturer. It may be appropriate to increase the test levels by a factor to allow for the maximum overshoot which is likely to arise on the voltage
45、 at the machine terminals, as described in IEC 60034-18-42. This factor may be as high as 1,7 for a 3-level converter but lower if there are more levels.

NOTE 2 The levels in Column 2 are obtained by using the formula: UP= 4 UN+ 5 kV. NOTE 3 The levels in Column 3 are based
48、 on an impulse having a front time of 0,2 0,1 s up to 35 kV. Above 35 kV, the front time is 0,2 s with a tolerance of +0,3 s/0,1 s. NOTE 4 The levels in Column 3 are obtained by application of the formula: UP= 0,65 UP.NOTE 5 The levels in Column 3 have been deemed appropriate for stresses related to
49、 circuit breaker operation that could occur in service. They may not be adequate for special operating conditions (e.g. interrupted start or direct connection to overhead lines). In such cases the windings should either be designed to withstand other impulse levels or be protected in an appropriate way. 4 Sample tests 4.1 General These tests are carried out as an indirect proof of compliance as explained in Clause A.3 of A
